[0024] In the embodiment, the S-shaped curved rainwater pipe 2 comprises a conventional rainwater pipe section, and a reverse U-shaped curved pipe section is arranged on the conventional rainwater pipe section; the conventional rainwater pipe section comprises a conventional vertical rainwater pipe, a horizontal rainwater pipe and the like, and the conventional rainwater pipe section and the reverse U-shaped curved pipe section are connected to form the S-shaped curved rainwater pipe 2.
[0025] In the embodiment, the rainwater and wastewater collecting device further comprises grooves 9 and a filtering device 10; the grooves 9 are respectively arranged on the roof drainage ditch 1 and the ground drainage ditch 3, and the filtering device 10 is inserted into the grooves 9, that is, the filtering device 10 is installed on the roof drainage ditch 1 and the ground drainage ditch 3 at the connection positions of the S-shaped curved rainwater pipes 2.
[0026] In the embodiment, the filtering device 10 comprises a fixed block 101, a sleeve 102, a threaded rod 103, a spring 104, a clamping block 105, and a filter screen 106. The fixed block 101 is rotationally connected with the sleeve 102, the threaded rod 103 is engagedly connected with the sleeve 102, the threaded rod 103 is slidingly connected with the fixed block 101, the spring 104 is located in the fixed block 101 and one end of the spring 104 is fixedly connected with the threaded rod 103, the other end of the spring 104 is fixedly connected with the clamping block 105, the clamping block 105 is slidingly connected with the fixed block 101, the clamping block 105 is inserted into the groove 9, and the filter screen 106 is fixedly connected with the fixed block 101. Such design makes the filtering device 10 removable. When the filtering device 10 is removed, the sleeve 102 on the fixed block 101 is rotated. Since the threaded rod 103 is slidingly connected with the fixed block 101, the threaded rod 103 cannot be rotated. Therefore, the rotation of the sleeve 102 can drive the threaded rod 103 to move towards the sleeve 102. The movement of the threaded rod 103 drives the spring 104 to move. The movement of the spring 104 pulls the clamping block 105 out of the groove 9. At this time, the filtering device 10 can be removed and the filter screen 106 can be cleaned. After cleaning, the sleeve 102 is reversely rotated to reset the clamping block 105. After the clamping block 105 is reset, the clamping block 105 is aligned with the position of the groove 9 and the fixed block 101 is pressed downward. The clamping block 105 is extruded into the fixed block 101 during the pressing process. Until the clamping block 105 is aligned with the groove 9, the spring 104 drives the clamping block 105 to fall into the groove 9, and the installation of the filtering device 10 is completed.
[0027] In the embodiment, the floating ball end of the floating ball valve 6 is located at the upper end of the collection tank 4, which can prevent the water in the collection tank 4 from being too full.
[0028] In the embodiment, the overflow pipe 11 is arranged on the collection tank 4 and fixedly connected with the upper end of the collection tank 4. The overflow pipe 11 on the collection tank 4 can prevent the occurrence of unexpected high water inflow in extreme cases, i.e., when the floating ball valve 6 fails or cannot respond to sudden increase in water inflow in time, a safe drainage path can be provided to avoid damage to the building or the surrounding environment and prevent water disasters. The overflow pipe 11 can be arranged with one or more pipes according to actual conditions.
[0029] In the embodiment, the collection tank 4 is provided with a partition plate 12 fixedly connected with the collection tank 4. The partition plate 12 separates water flows from different sources, better manages and utilizes the collected rainwater and wastewater, and optimizes the utilization of water resources. The relatively clean roof gutter 1 is preferentially used for purposes with higher water quality requirements, and storage and use are optimized.
[0030] In the embodiment, the S-shaped bend rainwater pipe 2 and the water outlet pipe 7 are connected to the lower end of the collecting pool 4, and the number of the water outlet pipe 7 can be set according to the actual situation.
[0031] The working process or working principle of the rainwater and wastewater collecting device is as follows:
[0032] The filtering device 10 is installed at the joint of the roof drainage ditch 1 and the ground drainage ditch 3 and the S-shaped bend rainwater pipe 2, and some impurities in the water are filtered by the filtering device 10. After the rainwater and wastewater is filtered by the filtering device 10, the rainwater and wastewater is collected into the collecting pool 4 by the siphon principle, and the water flows from different sources are separated by the partition plate 12, so that the collected rainwater and wastewater is better managed and utilized, the utilization of water resources is optimized, the water source of the relatively clean roof drainage ditch 1 is preferentially used for purposes with higher water quality requirements, the storage and use are optimized, the non-return valve 5 is installed on the S-shaped bend rainwater pipe 2, which can prevent the rainwater and wastewater in the collecting pool 4 from flowing back, when the rainwater and wastewater in the collecting pool 4 reaches a certain height, the float ball of the float ball valve 6 is driven to rise and trigger the corresponding mechanism, so that the excess rainwater and wastewater does not flow into the collecting pool 4, but flows to the municipal rainwater pipe network through the pipeline connected by the roof drainage ditch 1 and the ground drainage ditch 3, thereby avoiding the overflow caused by the overfilling of the collecting pool 4. In this way, not only the collected rainwater amount can be effectively managed, but also the water amount can be automatically adjusted to prevent the water level from being too high, thereby reducing the maintenance requirements of the system. The overflow pipe 11 on the collecting pool 4 can prevent the occurrence of an unexpected high water amount input in an extreme situation, that is, when the float ball valve 6 fails or cannot respond to a sudden increase in water amount in time, a safe drainage path can be provided to avoid damage to the building or the surrounding environment and prevent the occurrence of a flood. When the collected filtered rainwater and wastewater needs to be used, the stop valve 8 on the water outlet pipe 7 is opened, so that the rainwater and wastewater in the collecting pool 4 flows out through the water outlet pipe 7. When the filtering device 10 needs to be cleaned, the filtering device 10 can be pulled out of the recess 9, so that the filtering device 10 can be removed from the roof drainage ditch 1 and the ground drainage ditch 3 and cleaned. When the filtering device 10 is removed, the sleeve 102 on the fixed block 101 is rotated, the sleeve 102 is driven to move towards the sleeve 102 in the direction of the threaded rod 103, the threaded rod 103 is driven to move, the spring 104 is driven to move, and the clamping block 105 is pulled out of the recess 9. At this time, the filtering device 10 can be removed and the filter screen 106 can be cleaned. After the cleaning is completed, the sleeve 102 is reversely rotated to reset the clamping block 105. After the clamping block 105 is reset, the clamping block 105 is aligned with the position of the recess 9 and the fixed block 101 is pressed downward. The clamping block 105 is squeezed into the fixed block 101 during the pressing process of the fixed block 101, until the clamping block 105 is aligned with the recess 9. The spring 104 drives the clamping block 105 to fall into the recess 9, so that the installation of the filtering device 10 is completed, and the rainwater and wastewater can be collected by using the utility model.
